Apart from adding a page-size ACPI region in low memory, this patch
*removes* thirteen pages from the top of memory. Was that region just bogus?

The hvmloader code which copies the ACPI tables only checks that the tables
will fit into 0xEA000-0xEFFFF. Shouldn't e820 declare a region of that size,
therefore (i.e., 0x50000, not 0x10000)?
